WINDOW-REGULATING APPARATUS.

Application filed November 18, 1922. Serial No. 800,788.

To all whom it may concern:

Be it known that I, ANGELO ROBERT OLAS, a citizen of the United States,and a resident of Toledo, in the county of Lucas and State of Ohio, havemade an invention appertaining to a Window-Regulating Aparatus; and I dohereby declare the followmg to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the characters of reference markedthereon, which form a part of this specification.

This invention relates to window regulating apparatus particularlyintended for use in closed automobiles and other closed vehicles.

The object of the invention is the provision of a simple and efficientapparatus of the character described, which is easily operable to raiseand lower an associated window, is adapted to positively lock a windowagainst accidental lowering when in any position of adjustment, iscomposed of a few easily accessible parts, and is free from rattles.

The invention is fully described in the following specification, andwhile in its broader aspect, it is capable of embodiment in numerousforms, a preferred embodiment thereof is illustrated in the accompanyingdrawings, in which,

Figure 1 is an inner side elevation of an automobile door embodying theinvention with the upholstering removed, the window in partly loweredposition, and with portions broken away. Fig. 2 is a vertical section onthe line 22 in Fig. 1. Fig. 3 is an enlarged cross-section on the line3-3 in Fig. 2. Fig. 4 is a vertical section on the line 4-4 in Fig. 3,with a portion broken away. Fig. 5' is'a perspective view of a portionof one of the ratchet channel strips, and Fig. 6 is a cross-section onthe line 6-6 in Fig. 4.

Referring to the drawings, 1 designates an automobile door having in itsupper portion a window opening 2 and provided with a closure for said.opening in the nature of a vertically slidable glass plate 3 adapted,when lowered or removed to its open position, to enter a chamber 4 inthe lower portion of the door. The window is guided at its side edges bychannel strips 5 of felt or other suitable material adapted to preventrattling of the glass, and these strips are set into recesses providedtherefor longitudinally in the upright frame members or casing sides 6of the door.

The glass plate 3 fits at its lower edge into a metal channel strip 7,as is customary in w ndows of this type, the ends of the striptermmating short of the side guide strips 5 for the plate. An ear 8 isfixed to and projects downwardly from the edge strip 7 centrally of itsends and a cable 9 is anchored at one end to the ear, thence extendsupward therefrom over a sheave 10 carried withln the upper portion ofthe chamber 4 by a cross frame part 11 of the door, the cable extendingdownward from the sheaves and attaching at its opposite end to the freeend of a counter-balancin lever 12, which is pivoted at one end to aracket 13 secured to one of the frame sides 6 near its lower end. Thelever 12 extends across the chamber 4 substantially in a vertical planewith the lower edge of the window plate 3 and is acted on by a coiledcontractile spring 14 to counter-balance the weight of the window plate4. The upper end of the spring 13 is adapted to be placed in engagementat its upper end with any one of a plurality of notches 15 in the leverto adjust the tension of the spring with respect to the lever, and thelower end of the springis anchored to the cross-member forming thebottom of the chamber 4. This counter-balancing means for the windowplate is very efficient as the counter-balancing pressure of the sameagainst the plate is constantly exerted against the lower edge of theplate at its central portion, thereby eliminating any tendency of thecounter-balancing means to exert a lateral pressure on the plate tocause a binding of the same in its guides.

Each side frame upright 6 of the door or window casing, as the case maybe, is provided longitudinally thereof at the inner side of therespective guide strip 5 with a channel 16, which opens at what may betermed its outer side to the window opening 2 and the chamber 4. Achannel strip 17 preferably of metal, is .fitted into each frame barchannel or recess 16, or at least the portion thereof which opens intothe window opening 2, and preferably extends a distance down into theportion of the frame bar channel which opens into the chamber 4. Theinner side of each channel strip 17 is provided longitudinally thereofwith a series of ratchet openings or notches 18, while the outer side ofthe strip is provided with a longitudinally extending opening or slot19, which is restricted with respect to the width of the channel stripby an inward turning of the terminal edge portions of the channelstrips. This provides a ratchet strip of channeled or hollow form, whichis substantially rectangular in crosssection and provided longitudinallythereof in its inner or rear wall with .a set of ratchet openings ornotches 18, and in 1ts front or outer wall with a slot or elongatedopening 19.

The binding strip 7 for the lower edge of the window-plate 3 has an ear20 rigidly projecting from each end thereof into the adjacent door framechannel 16 and also into the associated ratchet strip 17 through thefront opening 19 thereof, should the ratchet strip extend down into thechannel 16 a sufii'cientdistance for such purpose. A

control or liftin rod 21 is mounted longitudinally in each ratchet strip17 and has its lower end pivotally connected to the adjacent car 20 ofthe window plate 3 for limited rocking movements in a planeparallel orsubstantially parallel to the face of the plate 3. The mounting of thecontrol rods 21 in this manner enables them to have inner and outerlocking'movements relative to the ratchet strips 17- or transversely ofthe window and within the confines of the ratchet strips.

Each control bar 21 is provided at the inner side of its upper endportion with a pawl or tooth member 22 for engagement within any one ofthe ratchet openings 18 with which it may register to coact with thelower wall of the opening to support the control rod in any position ofits vertical adjustment within the ratchet'strip. The tool 22 ispreferably carried by a stem 23. which pro ects outwardly through theassociated rod 21 and the ratchet strip 19 and is provided at its outerend without the ratchet strip with a handle 24. A spring 25, preferablyof bowed form, is disposed between the upper end portion of each controlrod 21 and the outer slotted wall of the associated ratchet strip 17 andacts to normally urge the upper end of the control rod toward the innerside of the ratchet strip and to retain the tooth 22 in engagement witha ratchetopening, as is apparent.

- To raise or lower the window plate 3 it is only necessary for theoperator to grasp the control handles 24 at each side of the windowcasing and draw them outwardly to efl'ct an outward rocking of thecontrol rods 21 against the tension of the springs 25 and a consequentwithdrawal of the ratchet teeth 22 from the engaged ratchet openings,after which a raising or lowering force exerted on the handles 24 willimpart a corresponding raising or lowering moveesa-lea ment to thewindow plate. If the ratchet teeth 22 are of the beveled face type, as

shown in the drawings, the window ma raised without first moving thecontrol andles to withdraw the teeth from the ratchet openings, as isapparent.

I wish it understood that my invention is not limited to any specificconstruction, arrangement, or form of the parts, as it is capable ofnumerous modifications and changes without departing from the spirit ofthe claims. and also that while I have particularly shown and describedthe window regulating -means in amociation with a door, it may beapplied to any window casing.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,-

window member mounted for raising and lowering movements in the casing,a control member disposed lengthwise of the window member and pivotedthereto, said control member having a tooth near its free end, andratchet means carried by the casing for coaction with the control membertooth to support the control and window members in difi'erent positionsof vertical adjustment.

2. In combination, a window casing, a window member mounted for raisingand lowering movements in the casing, a control member disposedlengthwise of the window member and pivoted thereto for rockingmovements in the plane of the window, said control member having a toothnear its free end, ratchet means carried by the casing for coactionwith'the control member tooth to support the control and window membersin different positions of vertical adjustment, and spring means actingon the control member to normally hold it in position for ber of saidmeans being pivoted to the window member and extending therefromlengthwise of the casing along the ratchet member of the means.

4. In combination, a window casing, a window member mounted for raisingand lowering movements in the casing, and pawl and ratchet meansconnecting the casing and window member, the ratchet member of saidmeans being carried by the casing and extending lengthwise of a sideportion thereof and the pawl member of said means comprising a rodextending lengthwise of the casing adjacent to a side edge of the windowand pivoted at one end to the window and having a tooth adjacent to itsother end for engagement with the ratchet member of said means.

5. In combination, a Window casing, a window member mounted for raisingand lowering movements in the casing, a chan neled ratchet strip carriedby the casing lengthwise of the window member and adjacent to a sideedge thereof, a control member mounted in the. ratchet strip lengthwisethereof and having one end pivoted to an adjacent edge of the windowmember and having a tooth adjacent to its other end portion for holdingengagement with the ratchet strip. 7

6. In combination, a window casing, a window member mounted for raisingand lowering movements in the casing, a channeled ratchet strip carriedby the casing lengthwise of the window'membermand adjacent to a sideedge thereof, a control memedge portion 0 ratchet strip, and meanswithin the ratchet strip and acting on the control member to normallyretain its tooth in holding engagement with the ratchet strip.

7 In combination, a window casing, a window member mounted for raisingand lowering movements in the casing, an elongated hollow ratchet stripmounted in a side of the casing lengthwise thereof and having ratchetteeth in one side and an elongated longitudinally extending opening inits opposite side. a control rod mounted in the ratchet strip lengthwisethereof and having one end fpivoted to an adjacent side the windowmember for locking movements transversely of the ratchet strip, said rodhaving a tooth near its free end portion for engagement with the ratchetteeth and having a handle part projecting without the ratchet strip tothe elongated opening therein, and means acting on the control barwithin the ratchet strip to normally retain the control bar ber mountedin the ratchet strip lengtl'lwise tooth in holding engagement with aregisthereof and having one end pivoted to an adjacent edge of thewindow member and having a tooth adjacent to its other end portion forholding engagement with the te'ring ratchet tooth.

In testimony whereof I have hereunto subscribed my name to thisspecification. ANGELO ROBERT CLAS.
